Free surface flows are common in the design and manufacture of consumer products used in both the home and office environment. Bottle filling is, for instance, a process which takes place on a large scale every day. Designing such a process to minimize waste while maximizing production speed can lead to significant cost savings over time. FLOW-3D can also be used to design spray nozzles, model absorptive capabilities of porous materials and other consumer goods components. FLOW-3D‘s advanced multiphysics models including air entrainment, porous media, and surface tension make it easy to accurately simulate and optimize consumer product designs.
